Spring-loaded seesaw**, which differs from the traditional pivot design seen in your previous photo. Here are its key features:
* **Spring Mechanism:** Unlike traditional seesaws that rely on a central fulcrum, this unit uses heavy-duty, coil-like springs mounted beneath the seats to provide a bouncing, spring-based motion.
* **Dual-End Design:** It is designed for two users, with designated seats at opposite ends of a central beam.
* **Safety Handles:** Each seat includes a U-shaped handrail, allowing the users to hold on securely while the spring mechanism is in motion.
